Themes in JasperReports Server are a mechanism to define and customize the user interface (UI) through Cascading Style Sheets (CSS), the web standard for defining the appearance of HTML content. A theme is the set of all CSS files and associated images that defines the appearance of the user interface. Themes are stored as file resources in folders in the repository, with special menus on theme folders for activating, uploading, and downloading a theme. You can store any number of themes in the repository, and administrators can switch between them, providing an easy and quick way to change the user interface.

For deployments licensed to use organizations, administrators can set the theme individually on each organization, or rely on theme inheritance to use the same theme everywhere without needing to set it explicitly. The inheritance mechanism also supports a mix of explicit and inherited settings, so that you can override any setting or image in a local organization, but inherit the rest of the theme from the parent or system-wide theme.

The theme mechanism was introduced in JasperReports Server 4.0, and the set of files in the default theme was updated in 4.7. Custom themes developed prior to 4.7 may require upgrading in order to work with the new set of files. For more information see the upgrade procedures in the JasperReports Server Installation Guide.
